The National Hurricane Center says Tropical Storm Peter has formed in the mid-Atlantic and will end up being a fish storm not affecting the U.S. mainland at all.
Earlier this morning, Peter began to encounter increasing southwesterly shear emanating from flow around an upper-level trough to its northwest.
This shear caused the low-level center of the storm to separate from the deep convection and as of now is located over 100 mi from the edge of that band of convection.
An Air Force Reserve Hurricane Hunter aircraft has been investigating the cyclone for the past few hours and has provided helpful data on the structure and intensity of Peter.
Based on the aircraft data, tropical-storm-force winds extend at least 100 n mi to the northeast of the center, while there are no tropical-storm-force winds in the
The initial wind intensity of 45 mph is based on aircraft passes through the northeastern quadrant that measured peak 925 mb flight-level winds of 56 and 54 kt.
